Donor vehicles with overlapping OEM specs

These are vehicle-year records whose recorded OEM ranges overlap this 2013 Audi A6. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.

Evaluated 188 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.

Dataset suggestionHub-centric rings ≈ 66.6 → 66.5 mm – not a verified installation requirement.

Hub-centric rings of about 66.6 → 66.5 mm mm may be relevant if the wheel bore is larger than the hub; they cannot enlarge a smaller bore. Approximate position vs the mid OEM package: outer change -0.17 mm, inner change -6.18 mm. This uses aggregated width/offset ranges, not a specific wheel.

2013 Audi A6 Wheel Fitment Guide

This page summarizes verified wheel and tire data available for the 2013 Audi A6 and explains how to use the on-page calculator to validate custom fitments safely. Some factory specs vary by trim, brake package, and wheel option. If any value is missing or looks inconsistent for your car, confirm it with the calculator and OEM sources listed below before buying parts.

Note: The wheel size listed above shows a 19 inch rim while the tire entry shows an 18 inch diameter. That indicates multiple OEM packages were offered on the 2013 A6. Your exact factory size may differ by trim or option. Use the calculator to compare what is on your vehicle now to any potential replacement and verify against OEM sources.

How to confirm your exact OEM sizes

  • Check the driver door jamb tire and loading label for OEM tire size, load index, and speed rating.
  • Look in the owner manual for factory wheel dimensions and offset notes.
  • Call an Audi parts department with your VIN to confirm wheel option codes, brake package, and fastener seat type.
  • Compare your current setup in the on-page calculator against the known OEM values above to spot differences.

Using the Wheel Interchange Calculator on wheelinterchange.com

The calculator compares Wheels from (donor vehicle) to Installed on (your vehicle) and lets you try a Custom wheel size and Custom tire size.

  • Select 2013 Audi A6 as Installed on (your vehicle).
  • If you are considering a takeoff set, pick that vehicle under Wheels from (donor vehicle). If not, use Custom wheel size.
  • Enter rim diameter, width, and offset. The tool updates backspacing and inner clearance automatically.
  • Enter a tire size. Changing rim diameter updates overall tire diameter in the comparison view.
  • Review inner clearance to suspension and brake hardware and outer poke relative to the fender. Lower ET moves the wheel outward, higher ET moves it inward.
  • Ensure overall tire diameter remains close to your OEM to keep speedometer and electronic aids behaving as expected.
  • If your aftermarket wheel hub bore is larger than 66.6 mm, select or source the proper hub centric rings so the wheel is centered on the hub.

Safety and clearance checks before you buy

  • Brake caliper clearance. Verify spoke and barrel clearance using the calculator and, if possible, a physical test fit.
  • Inner fender and suspension. Watch strut, spring perch, control arms, and liners at full lock and compression.
  • Fender and bumper lips. Outer poke must not contact the arch during bumps or steering.
  • Offset changes. Small changes can significantly affect clearance. Use the tool to quantify inner clearance loss or gain and outer position change.
  • Load rating. Wheels and tires must meet or exceed the A6 axle loads. Match the load index shown on your door label.
  • Hub centering. The A6 hub bore is 66.6 mm. If the wheel bore is larger, use quality rings sized 66.6 mm to your wheel bore.
  • Fastener interface. Thread size is M14 x 1.5. Verify lug bolt seat type for your wheels. OEM Audi wheels often differ from some aftermarket designs, so match ball vs cone seat exactly.
  • TPMS. Reuse or replace sensors as required by the wheel and tire package. Follow Audi procedures for system setup after installation.

Hardware notes for the 2013 Audi A6

  • Stud pattern is 5x112 and the vehicle uses lug bolts, not lug nuts.
  • Thread size M14 x 1.5 is provided above. Length and seat type must match your wheel design. Do not mix seat types.
  • Center bore is 66.6 mm. Wheels with larger bores require hub rings. Wheels with smaller bores will not fit the hub.
  • Wheel torque and bolt length vary by wheel and brake package. Always follow the torque spec in your owner manual or Audi service information.

Installation checklist

  • Clean hub faces and wheel mounting pads. Remove rust and debris.
  • Confirm bolt seat type and length. Hand start all bolts to avoid cross threading.
  • Tighten in a star pattern. Use a calibrated torque wrench to the Audi spec for your vehicle.
  • Verify free rotation and clearance at full left and right lock before road testing.
  • Recheck torque after a short shakedown drive and again after some miles of use.

Common questions

Can I use 18 inch wheels if my car came with 19s? Many trims offer multiple OEM sizes, but verify brake caliper clearance and overall tire diameter with the calculator, then confirm against your door label and Audi documentation.

Will different offsets affect handling or wear? Yes. Moving the wheel inward or outward changes scrub and bearing loads and can cause rubbing. Use the calculator to measure inner clearance and outer poke changes, then choose conservatively.

Helpful tools and parts

Key takeaways

The 2013 Audi A6 uses a 5x112 pattern, 66.6 mm hub bore, and M14 x 1.5 bolts. OEM wheel and tire sizes can vary by trim, and the values shown here indicate that multiple factory packages existed. Always verify your exact OEM size on the door label and in the owner manual, then use the calculator to model any custom wheel or tire so you can confirm clearance, maintain proper load rating, and preserve vehicle safety systems.

Methodology and sources

Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:

  • Bolt pattern / PCD
  • Center bore direction (donor wheel bore must not be smaller than the hub)
  • Wheel diameter, width, and offset against known OEM ranges
  • Lug thread / hardware differences (vehicle-side hardware)

A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
